1021 One can configure more than one IPv4 address with the

1024 One or more IP addresses must be provided in Classless Inter-Domain

1027 In this case the address 192.168.0.5 will be configured with the
1028 netmask /24 and the addresses 192.168.0.6 to 192.168.0.23 with
1029 the non-conflicting netmask /32 as explained in the

1034 an example could look like:
1036 ipv4_addrs_ed0="192.168.0.1/24 192.168.1.1-5/28"
1039 It is also possible to add IP alias entries using
1042 Assuming that the interface in question was
1045 something like this:
1047 ifconfig_ed0_alias0="inet 127.0.0.253 netmask 0xffffffff"

1112 Also, if your interface needs WPA authentication, it is possible to add
1115 .Va ifconfig_ Ns Aq Ar interface
1118 Finally, you can add
1120 options in this variable, in addition to the
1121 .Pa /etc/start_if. Ns Aq Ar interface
1123 For instance, to initialize the
1125 device via DHCP, using WPA authentication and 802.11b mode, it is

1139 This is intended to replace the no longer supported

1154 they should be set as

1156 Aliases should be set as
1157 .Va ipv6_ifconfig_ Ns Ao Ar interface Ac Ns Va _alias Ns Aq Ar n .
1158 .Va ipv6_prefix_ Ns Aq Ar interface
1160 Interfaces that do not have a
